Two’s company,three’s a crowd: disabled people,their carers and their partners

In this analytical autoethnography, I share some of my complex relational experiences between my partner with a severe physical disability, his carers and myself. The article explores the benefits of care and carers, the physical and emotional costs of carers and some of the general considerations taken in this triad relationship. I share some of my relational experiences with an audience who might not normally encounter or have thought about the dynamic relationships between this triad. It is hoped that this will stimulate an interest to open dialogue, offer support and provide an insight into the lives of some relationships.     

论“严打”的犯罪学根据及其实践的若干问题

意大利著名犯罪学家菲利的"犯罪饱和法则"是"严打"刑事政策的犯罪学根据。在法治国进程中,实施严打必须依法进行,包括严格遵守实体法和程序法;要合理界定严打对象,要实现严打的人权保障宗旨。"严打"的价值和作用,现有积极的意义又不可估价过高,要把"严打"和"惩治"结合起来,才能既治标,又治本。

False Alarms and Missed Events: The Impact and Origins of Perceived Inaccuracy in Tornado Warning Systems

Theory and conventional wisdom suggest that errors undermine the credibility of tornado warning systems and thus decrease the probability that individuals will comply (i.e., engage in protective action) when future warnings are issued. Unfortunately, empirical research on the influence of warning system accuracy on public responses to tornado warnings is incomplete and inconclusive. This study adds to existing research by analyzing two sets of relationships. First, we assess the relationship between perceptions of accuracy, credibility, and warning response. Using data collected via a large regional survey, we find that trust in the National Weather Service (NWS; the agency responsible for issuing tornado warnings) increases the likelihood that an individual will opt for protective action when responding to a hypothetical warning. More importantly, we find that subjective perceptions of warning system accuracy are, as theory suggests, systematically related to trust in the NWS and (by extension) stated responses to future warnings. The second half of the study matches survey data against NWS warning and event archives to investigate a critical follow‐up question—Why do some people perceive that their warning system is accurate, whereas others perceive that their system is error prone? We find that subjective perceptions are—in part—a function of objective experience, knowledge, and demographic characteristics. When considered in tandem, these findings support the proposition that errors influence perceptions about the accuracy of warning systems, which in turn impact the credibility that people assign to information provided by systems and, ultimately, public decisions about how to respond when warnings are issued.     

弹性支承圆弧钢浅拱弹塑性极限承载力分析

实际工程中许多拱结构支承于其他结构之上，下部结构对拱脚的约束并非完全刚性，在这种情况下拱脚约束可以简化为水平和转动弹性约束。采用ANSYS有限元分析软件，在考虑初始缺陷、几何非线性和材料非线性的基础上，针对工字形截面水平和转动弹性支承圆弧钢拱进行了参数化分析。研究了不同荷载工况下水平和转动弹性支承拱的弹塑性极限承载力、极限状态下拱脚的支座位移，对已有的设计公式进行了修正。

对"舞蹈是流动的雕塑"的质疑

"舞蹈是流动的雕塑",这句话不能看作定义,它是在局部相似的基础上产生的整体类比,这个相似之处就是它们都有人体姿势。但由于媒介的根本异质,舞蹈姿势与雕塑姿势也相应地有所不同,其外观甚至完全相反。人体姿势构成雕塑作品的全体,其意义永恒不变,但舞姿只是构成舞蹈作品的元素,不具备独立的价值,其意义常处在变化之中。舞蹈确实是"流动的",却不是"雕塑的"。雕塑是再现性艺术,舞蹈是表现性艺术;雕塑是造型艺术;舞蹈是表演艺术。
